Application filed January 8, 192-3. Serial No. 611,295.

T 0 all whom it may concern.

Be it known that l, Mmrrin SWINTEK, a citizen of the United btates of America,

and resident of Eddyville, lVapello County,

Iowa, have invented a new and useful Hoisting and Loading Conveyor, of which the :tollou'ing is a specification.

An object of this invention is to provide unimproved construction tor. a hoisting and loading conveyor mechanism.

A. further object of thisinvention is to provide an nnproved s1ngle-cable,-auto matic-duinp hoisting conveyor for use with granular substances such as sand, gravel or shelled grain.

A, further object of this invention is to provide improved means "for mounting a scoop or bucket to facilitate the operation of picking up, hoisting and (lQPOSllZlDg loose granular substance. i

7' A further object of this invention is to provide improved means for automatically dumping the scoop or bucket when it has reached a certain altitude.

A further object of this invention is to provide means "for automatically inverting the scoop or bucket when it has been hoisted to a certain altitude, latching 1t 1n" inverted position during its descent, and automatically releasing it whereby it may assume the proper position for receiving another load when it has reached the bottom of the the carriage and the scoop in position for dumping. Figure 5 is a similar view show ing the carriage after it has started to descend, with the bucket latched in inverted position.

In the construction of the mechanism as shown a frame is provided which is rectangularly prismatic in form and composed primarily of corner posts 10,11 connected toward the carriage 16.

byside bars 12 and cross bars 13 and editably braced. The frame may be of any suitable (size and of any desired height to raise substance to the necessary elevation for depositing it required for the particular needsjof the location. Opposed tracks 14 15are provided, arranged vertically and extending substantially from the bottom to the to of the frame and carriedb the side bars 12. "The tracks 14,15 may be formed of spaced bars" as shown, or they may be composed of channel beams arranged with their channels openi ng inwardly toward each other, on. opposite s des of the frame. A, carriage,

" designated generally by the numeral 16, is

arrangedtransversely o i the frame and is adapted fonvertical sliding movement in the tracks 14:, 15; In the event the tracks are formed of channel beams the carriage may be received bodily within the channels;

out in the present instance it is shown as havin vertical ton 'ues 16" ro'ectin fromi b a its opposite sides between the spacedfbars forming thetracks. Carried by one side ot the carriage 16, which will be considered the rear side, are spaced bearings 17 carrying a horizontal rod or spindle 18. A scoop or bucket 19 is provided'having a substantially horizontal bottom; and closed at its rear and sides but open at the opposite side 7 Arms 20, 21 are fixed rigidly to' thesides of the scoop or bucket 19, near the rear wall thereof, and

said arms are pivoted at their free ends on the rod or spindle 18. The arms are con nected by cross bars 22. mounted between them and also by a rod 23'extend1ng across thcirfouter or rear faces andprojecting at itsends beyond said arms, rollers 24, 25

being journaled on'the projecting ends of said rod. A cable 26 is fixed at oneend to the central portion of the rod 23 and is thus connected to. thescoop, passes forwardly through an aperture in the carriage 16, en-

gaginggadirection' pulley 27 journaled in said aperture, thence upwardly through the top of thecarriage. The cable 26 passes upwardly'to the top of the frame and over a sheave. 28 carried by said frame or by a bracket such as 29 rising above theframe.

The cable 26 then passes downwardly through the frame to the desired location for applying draft thereto, which may be by 'means' of an engine and drum (not shown) 5 and said cable nay pass overallother direction pulley such as located at or near the bottom of the frame andextend in any desired direction therefrom.

Side plates 31, 32 are carried by opposite sides of the frame at about the desired elevation for dumping the scoop or bucket 19, and a chute 33 extends downwardly and rearwardly from a point beween said plates, projecting outside of the frame between the posts 11 and extending to a suitable point. of delivery, which may be to a car or wagon, or to a hopper communicating with sand and gravel washing and screening devices. Scoop dumping and inverting devices are mounted on and carried by the inner faces of the plates 31, 32, one set of which is shown in Figures 4 and 5 as carried by plate 31, and it is to be understood that duplicates of such devices are mounted in opposed relation on the inner face of plate 32. The set of such devices shown will now be described in detail. A deflecting trigger 34 is pivoted at one end, by a bolt 35, to the plate 31, near the track 14, and the free end of said trigger is beveled on its lower face and projects across the path of travel of the roller 24 on the scoop arm when said scoop is raised as hereinafter set forth. The trigger 34 is held in a position inclined upwardly toward the track 14 by means of a stop pin 36 seated in the plate 31, and upward movement of said trigger is limited by a stop 37 carried by said plate near the pivot bolt 35. The upper face of the trigger 34 serves as a track for the roller 24 at times, and a short track member 38 is rigidly mounted on the plate 31 in continuation of said trigger and also inclined downwardly away from the track 14. A longer track member 39 is fixed to the plate 31 beneath the trigger 34 and track member 38 and is oppositely inclined. The track member 39 is spaced somewhat below the lower end of the short track member 38 at a point substantially above the upper end of the chute 33. and thence extends inwardly and downwardly toward the vertical track 14. terminating at a point spaced somewhat from said vertical track. A vertical guide '=is fixed to the plate 31 and extends downwardly in a substantially vertical plane from thelower end of the longer track member a suitable distance.

In practical use, starting with the carriage I the like, is located within the lower end of the frame and between the lower ends of -the vertical tracks 14, 15, d-raft'is applied to the cable 26v in the manner provided. The first effect of such draft on 'the cable, through its connection to the scoop through the cross rod23, is to pull said scoop toward the car riage 16, thus loading said scoop with 9.

quantity of the substance located at the lower end-of the frame. In the loading operation the scoop arms 20, 21 gradually move to substantially vertical position, the carriage 16- moving upwardly in the tracks 14, 15 as said arms move through an arc, until the forward portion of the scoop is located beneath the carriage, in which position the arms 20, 21 are in contact with the carriage and the attached end of the cable 26 is located adjacent the direction pulley 27 in said carriage. Continued draft on the cable '26 will cause the carriage and scoop, with its load, to be raised, the carriage traveling upwardly in the vertical tracks 14, 15. The rollers 24, 25 pass upwardly between and adjacent the inner faces of the plates 31, 32 and as they contact the beveled inner ends of the deflecting triggers 34 said triggers are oscillated suiiiciently to permit passage of said rollers, which when they have cleared permit the triggers to fall back to positions of rest on the stops 36. Thereafter draft on the cable 26 is released, as by unclutching the drum on which it is being wound, and the carriage and scoop,-with its load, are permitted to descend by gravity until the rollers 24, 25 engage the upper surfaces of the deflecting triggers 34. Continned descent of the carriage causes the scoop 19 to be moved through an are away from its depending position as the rollers 24, 25 travel downwardly and outwardly on the upper faces of thetriggers 34 and thereafter on the short tracks 38. the scoop 19 to be gradually moved to dumping position, with its open end downward over the upper end of the chute 33, into which the contents of the scoop are dis; charged. lVhen the rollers 24, 25 reach the outer ends of the tracks 38 they drop ofl upon the longer tracks 39, the shock of such drop serving to dislodge any of theload which may have remained in the scoop, which is shown in this position in Figure 3. The bearings 17 and spindle 18 ofthe carriage have now passed below the 'horizontal plane of the rollers 24, 25,.'so that continued downward movement of the carriage causes a downward draft on the arms 20, 21, the rollers traveling downwardly and forwardly on the longer inclined tracks 39 until saidv arms have assumed substantially vertical position with the scoop uppermost and inverted. The scoop continues its descent in this position, being held temporarily by contact of the rollers with the vertical guides 40.

thetop of the carriage 16. The latching arms are formed with notches 43' on their This causes site ends the latching arms 41, 42 are connected respectively to vertical bars 44, 45 which are arranged for .vertical sliding movement in slide bearings formed in the forward face of the carriage 16, said sliding bars extending a material distance below said carriage and preferably being connected at their lower ends by a cross bar or brace 46.

The sliding bars 44, 45 may be limited as to downward movement in the carriage by means of sto shoulders or lugs 47 adapted to engage tie top of the carriage. The latching device is gravity operated and au tomatically engages the cross bar 22 when the arms are carried into vertical position, serving to hold the arms and sc0op,inthis position until the carriage has descended to the bottom of the frame. Just before the carriage reaches the bottom the lowerends of the sliding bars 44, 45, or the cross-bar or brace 46 thereon, engage the ground surface,

or the pile of sand or other "substance thereon, stopping descent 'of thelatching devices,

and as the carriage and scoop continue to descend thelatch arms are disengaged from the cross-bar 22 of the scoop arms and the scoop 19 is permitted to move through an are, through force of gravity, to position for receiving another load:-that is, to substantially the position of Figure 1. The sliding bars 44, 45 preferably are braced by a crossbar 48 connecting them attheir upper ends,

It will be observed that but a single cable is necessary for the operation of the device, that is to say the loading and hoisting cable 26; the operation of dumping the scoop being accomplished automatically upon releasev of the cable after the scoop has reached a certain elevation, and the scoop being automatically returned to position for loading upon reaching the bottom of the device.
